Programming

Setting Time

Press the SET button. Use the UP or DOWN buttons to set the day of the week, then the hour, and finally the minutes. Press SET or wait 10 seconds to confirm.

Setting Economic/Comfort Temperature

Press the MODE button. Use the UP or DOWN buttons to adjust the temperature. The display will show the currently set temperature. Press MODE or wait 10 seconds to confirm.

Selecting Factory (1-6) and User (7-9) Programs

Press the PROG button. Use the UP or DOWN buttons to select the program number (1-6 for factory, 7-9 for user-defined) for the selected day(s). You can program each day separately, business days and weekend (5+2), or the whole week (7). Press PROG to confirm.

Auto-Adapt Feature

This function adjusts the heating device's operation to ensure the comfort temperature is reached at the specified time. The auto-adapt feature activates when the room temperature is lower than the comfort temperature in the upcoming program. The pre-heating time, ranging from 10 to 50 minutes, depends on the temperature difference. A larger difference results in earlier activation.

Antifrost Mode

Simultaneously hold down the MODE and PROG buttons to activate the 7°C Antifrost Mode (heating only). This mode remains active until the next scheduled program change. To exit, press any button.

Service Parameters

Service parameters can be adjusted using DIP switches numbered 1-3 located inside the thermostat.

• DIP Switch #3: Selects Heating (ON) or Cooling (OFF) mode.
• DIP Switches #1 and #2: Adjust hysteresis (span). Possible values are 0.4°C, 0.8°C, and 1.4°C.

Changing the Communication Code (T105RF)

To prevent interference from other wireless devices, it is recommended to change the factory communication code. Use DIP switches numbered 1-5 inside the thermostat. Set the DIP switches randomly, ensuring they are in the same position on both the receiver and transmitter. After changing the code, press the RESET button on the thermostat to register the new code.
